Theedges 7a, 7b are preferably sharpened Figure 6 is a side view of Figure5 taken from to provide cutting edges on the cap 9 for the 5 purpose ofshearing off the projection from the end of the tube.

This arrangement of parts enables the tube to be maintained in anair-tight condition until the contents are to be used. It is readilyunderstood that by revolving the aperture '7 of the cap 9 to a pointdiametrically opposite to the aperture 16 the cap 9 keeps the aperture16 closed, preventing egress of the tube contents. The cap 9 isdome-shaped so thatwhen the slot 7 is in the position last described,the aperture 6 is in a position as remote as possible from the aperture16 of the tube so that any material within the tube can only find anexit by travelling along the dome-shaped top 5 of the tube neck 3 to theaperture '7.

It will be noted that on the base 17 of the tube 1 that there ishingedly mounted a supporting wire 18 having a bulged portion 19,adapted to be used as a means for hanging up the tube either on a hookor in the slot of a tooth brush holder.

20, of the type shown in Figure 9. As the contents of the tube 1 areused, the lower end of same may be rolled upon itself upwardly as seenin Figure 1, the wire 18 being loosely and revolubly mounted at points21 and 22 on the tube. It is also seen that when the tube is shipped thewire 18 may take the dotted position 23, shown in Figure 1.

In Figures 5 to 8 inclusive of the drawing, is illustrated a modifiedform of container closure, in which 24 is the tube, 25 is the neck ofsame, which is provided with an annular exterior recess 26, and a closedend 2'7, which last is provided with a partially cut slot 28 for egressof the tube contents. Mounted on the tube neck 25 is the cap 29 whichhas an annular inwardly formed groove 30 thereabout. A spring wire 31,clearly illustrated in Figure 8 and preferably formed of a single lengthof wire, is used as a means of carrying the cap 29 on the neck of thetube 25. It is seen from the drawing that the cap 29 may be readilysprung into the loop 32 of the wire, and the lower loop 33 of same maybe sprung about the neck of the tube 25 and lodged in the annular groove26. A small recess 34 is provided on the one side of the neck 25 of thetube in which the spring catch 36 mounted on the cap 29 engages when thecap is in closed position, as shown in Figure 5 of the drawing. When thecatch 36 is freed from the recess 34, the spring in the wire 31immediately lifts the cap to the position shown in Figure 6. The meansjust described, of attaching the cap to the neck of the tube preventsthe cap from being lost, and also holds same in proper position topermit the contents of the tube 24 to be ejected through the opening 28,in the upper end of the neck of the tube.

Attention is called to the fact that before the tube has been firstopened, the aperture 28 is kept closed by the soft metal used for thebody of the tube, but the outline of the slot 28 is partially cutthrough the tube material, so that by the use of a pointed instrumentthe aperture 28 can at once be opened ready for use. In this way asubstantially hermetically sealed tube is provided, as in the case ofthe tube first described in this specification.

We claim:

1. In a container, a tube having a closed top thereon, a rotatablenon-removable cap of comparatively hard material mounted on the top ofthe tube and provided with an aperture therethrough, a pair of cuttingedges formed in the the cutting edges of the same, and form an aperturein the top of the tube which can be registered with the cap aperture,for dispensing'the tube contents, and which can also be placed in aposition of non-alignment with the cap aperture, for preventing egressof the tube contents.

2. In a container, a tube having a closed top thereon, an integralprojection of comparatively soft and thin material formed on said topportion of the tube, a rotatable non-removable cap of harder materialthan that of the integral projection, having an aperture therethroughsurrounding the latter, a pair of sharpened, opposed cap edges adjacentto the cap aperture, adapted to shear off the projection material uponrevolution of the cap, and make an aperture in the top of the tube whichis registrable with the cap aperture whereby the tube contents may bedispensed.

3. In a container, a tube having a closed top thereon, an integralclosed projection formed on the top portion of the tube, a rotatablenon-removable cap having an aperture therethrough, surrounding theintegral projection, sharpened cutting means on the cap adjacent to thecap aperture, adapted to shear off the integral projection, and make anorifice in the top of the tube when the cap is revolved for dispensingthe tube contents; and detachable means mounted on the base of the tube,for suspending the tube when not in use.

4. In a container, a tube having a closed top thereon, an integralclosed projection formed on the top portion of the tube, a rotatablenon-removable cap having an aperture therethrough, surrounding theintegral projection, and sharpened cutting means on the cap adjacent tothe cap aperture, adapted to shear off the integral projection, and makean orifice in the top of the tube when the cap is revolved, fordispensing the tube contents.

5. A device including a container having a wall provided with a seatingportion, said wall having an offset portion at said seating portion, anda closure member seated on the seating portion for movement along apredetermined path, said closure member having means for severing saidoffset portion at one point in said path to afford a discharge openingthrough said wall, said closure member being movable to another point insaid path to close said opening.

6. A closure including a wall of a material of low shearing strength andhaving a seating surface, said wall having an integral closed ended thinwalled projection at said seating surface, an element of thin sheetmaterial seated on said seating surface and having an opening forreceiving said projection, said element and wall being movablerelatively to each other along said seating surface to cause an edge ofsaid opening to sever said projection along the plane of the seatingsurface so as to afiord a portin said wall, and said element beingadapted to constitute a closure for said port as a result of thecoaction of the wall and element at the seating surface and the relativemovement therebetween, and the top of said projection lyingsubstantially in the plane of said element.
